Is ppm important????

[auggystyle]

im a first time grower, im having problems with my plants....how important is the ppm....how do i raise or lower it...i use deer park spring water....


Water is judged by taste. The Total Dissolved Solids (TDS) of the water primarily affect taste and are measured in mg/liter(parts per million). The other leading influence on taste is temperature.
The easiest way to determine what the taste of water is to find out the TDS of the water. A scale of 0 to 500 is used by US manufacturers with waters over 500 being called mineral water. Zero is a distilled water, which means there are no minerals found measured to parts per million. Zero does not mean absolutely zero, it means zero per million.
· Shenandoah Distilled Water is 0 ppm
· Shenandoah Spring Water is 92 ppm
· Shenandoah Fluoridated Spring Water is 93 ppm
· Deer Park Spring Water is 95 ppm
· Mountain Valley Spring Water is 268 ppm
· Perrier is 500ppm
· San Pellegrino is over 1,000ppm.

The PPM range for my plants is between 800-1200(those being the two extremes)

Adding nutrients will raise the PPM
